How do I use CSF to redirect domain requests to a port?

Question

I have a server setup that uses two different webservers with different subdomains. Right now the servers listen on different ports (80 & 4000)

So users don't have to put in :4000 I'd like to have a traffic from a different domain route port 80 traffic to the 4000 port through CSF.

I have a wildcard redirect setup so *.mydomain resolves to my server.

Right now it works like this:

• user navigates to http://www.myexample.com and is served a WordPress app.
• user navigates to http://test.exampleDomain2.com:4000 and is served by a custom Node app.
• user navigates to http://testAgain.exampleDomain2.com:4000 and is served by the same custom Node app.

I want it to work the way it does now except enable users to leave off the port.

• ie. http://www.myexample.com = > still served by WordPress
• http://testAgain.exampleDomain2.com => served by custom app (no port 4000 required)

We already have CSF installed so I'd prefer a solution using that.

EDIT: looks like CSF redirects operate on ip addresses not http hostnames.

You need to do this on web server. Try with a reverse proxy
